The Holtek HT32F675x5 device is a high performance, low power consumption 32-bit microcontroller based around an Arm Cortex-M33 processor core and with an Arm Cortex-M0+ co-processor core which runs the lower layer of the BLE and 2.4G protocol stack. The Cortex-M33 is a next-generation processor core which is tightly coupled with Nested Vectored Interrupt Controller (NVIC), SysTick timer, and including advanced debug support.
The device operates at a frequency of up to 64 MHz with a Flash accelerator to obtain maximum efficiency. It provides up to 1024 KB encryptable in system Flash memory with 16KB cache controller for code/data storage, up to 256 KB of embedded SRAM memory for system operation and application program usage and up to 256KB of embedded ROM memory for preprogrammed embedded RTX-RTOS kernel, driver library, and BLE lower layer protocol stack software. A variety of peripherals, such as BLEC, 2P4GC, DMAC, STTM, GPTM, WDT, RTC, USB, SPI, DSPI, QSPI, UART, I2C, SCI, IrDA, I2S, PCM, AES128, TRNG, QEI, KBC, ADC, TSEN and SW-DP (Serial Wire Debug Port), etc., are also implemented in the device. Several power saving modes provide the flexibility for maximum optimization between wake-up latency and power consumption, an especially important consideration in low power applications.
The above features ensure that the device is suitable for use in a wide range of BLE products such as handheld products, health care products, home appliances, smart device information beacons, data loggers, human interface device service, etc.
